To all whom it may concemi Be it known that I,"F ANoEs M. WAY, .a

citizen of theUnited States, residingatDetroit, county of 'Wayne, State of Michigan,

have invented a certain new and useful Im- I proven1ent Invisible Ear-Drums, and declare the following tobe a full, clear, and

exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings,

which form a part of this specification.

My invention relates to an improvement in invisible ear drums, shown in the accomear and to serve as a support for the ossicles,

while its extreme endaifords an adequate bearing or contact pointfor connection with -upon the drawmgsf-A indicates the audi- .tory'canaLB the'tympa'nic'membrane, and C the ossicl'es. I

1) denotes the drum preferably formed of 'in position in the ear.

the inner wall of the ear. =Its eculiar shape also provides fora chamber esigned to receive a medicinal preparation intended for use in the treatment ofthe ear by locaLapplications. i I

Another feature of the construction isthe contracted cylindrical stem connecting the cup and bulb-shaped portions, the stem b e-.

ing designed to pass through the opening'm the ruptured tynipanum', while the flaring cup-shaped port-ion snugly fits the wall of the auditorycanal thereby sealing the opening into the tympanic cavity and thus preventing the too rapid evaporation of moisture from the surface of'the tympanic'membrane.

Another feature is the bead or thickened edge given to the cup-shaped portion, which serves --to maintain its circular form and provide a suitable gripping edge for the tweezers when removlng or, replacing the drum.

In the drawings: Figure 1 shows the drum Fig. 2 is an enlarged side elevation of the device. Fig. 3 is a longitudinal central section of the same.

-' Referring now to the letters of reference rubber, consisting ofa cup-shaped portion D formed with a beaded outer edge (1, and

approximately parabolic form.

--medicinal preparation E,

' portion,

' ing .the bulbous a ta ering inner wall d. Connected with the. inner wall d .is a relatively, contracted tubular portion D designed to project through the ruptured tympanum. The wall of the drum atd tially right angles to the tubular portion-D shaping itself into a bulbous portionD of \Vithin the bulbous-shaped portion is lodged a suitable designed for localized treatment of. the ear; 7 D denotes an orifice at the end of the portion D through which the; medicament passesto the car.

It will be readily understood that the bulbous shape given to the chamber D serves to collapsing.

Having thus described my invention, what I claim is 2,- a

1. In an ear drum, an open cup-shaped a chamber adapted to contain a' portion, lnedicinalpreparation, and a tubular stem connectlng'the said chamber with the cup? shaped portion, said chamber having a relativel whic the medicinal preparation may be dissmall opening jinone end through charged.

2. In an ear drum, a cup-shaped portion,

carry a medicinal preparation, and a hollow stem connecting the cup-shaped portion "with the bulbous portion, the Wall of the bulbous portion provided with a contracted aperture to permit of a discharge of' the medicine from the bulbous portion.

3. Inan ear drum, a cup-shaped portion,. a hollow bulbous. portion adapted to carry a medicinal preparation, a relatively long tubular stem projecting from-the bulbous and a tapering inner' wall connecting the cup-shaped portion with the tubular stem.

4. In an ear drum, a cup-shaped portion provided with a'beaded outer-edge and a tapering inner wall, a tubular portion projecting from the tapering inner wall, and a hollow bulbous portionconne'ct'ed with the tubular portion, said bulbous portion provided with a single aperture atone end for the discharge of a medicinal preparation.

5. In an ear drum, -a cup-shaped portion, a hollowbulbous portion of substantiallyparabolic form, and a tubular stem'connectportion with the on -shap ed portion,.said bu bous portionprov ed with flares outward at= substan-- keep the wall of the chamber from .a hollow bulbous-shaped portion, adapted to a contracted aperture for the discharge of a medicinal preparation.

6. An ear drum comprlsing a cup shaped portion whose free edge is beaded and-'whose inner edge tapers, a tubular stem projecting from the tapering part of the cup shaped portion, and a hollow bulbous portion connected to the tubular portion, said bulbous portion at its base end being formed at a direct right angle to said tubular stem and having-a perforation at its free end in alinement with the tubular stem.

7. An cup shaped portion, adapted to fit snugly in the auditory canal of'the car, a hollow bulbous shaped portion adaptedto contain a inedioinal preparation, and a hollow stem connecting the cup shaped portion with the bulbous portion and adapted to project through the ruptured tympanum of the ear,

the wall of the bulbous with a single perforation.

- 8. An ear drum comprising a cup shaped portion, a hollow bulbous shaped portlon adapted to contain a medicinal preparation,

portion provided ear drum comprising a yieldable] and a hollow stem connecting the cup shaped portion with the bulbous portion, the bulbous portion having a perforation in alinement with said hollow stem.

9. An ear drum comprising a cup shaped sound receiving portion, a hollow bulbous portion adapted to carry a medicinal prep- I aration, and a hollow sound conducting stein connecting the cup shaped portion with the bulbous portion, the wall of the bulbous por- 1 tion where it connects with said hollow stem 3 being disposed at a right angle to the hollow stem and gradually tapering outwardly from the stem with its outer tapering end provided with a perforation. the medicinal preparation being normally below the perforation and discharged through the perforation.

In testimony whereof, I sign this specification in the presence of two witnesses. FRANCES M. WAY. I Witnesses:
